A week after the Rothken law firm filed a federal class action lawsuit against SCEA with regards to the PlayStation Network breach, Toronto law firm McPhadden Samac Tuovi LLP has commenced its own lawsuit against the company.

The Canadian law firm is claiming damages in excess of $1 billion against Sony Japan, Sony USA, Sony Canada and other Sony entities. The company alleges "breach of privacy" and claims that Sony must "pay the costs of credit monitoring services and fraud insurance coverage for two years."

The lead plaintiff in the lawsuit, Natasha Maksimovic, is a 21 year old Mississauga resident. In a statement, she noted, "If you can't trust a huge multi-national corporation like Sony to protect your private information, who can you trust."

"It appears to me that Sony focuses more on protecting its games than its PlayStation users," she said -- an apparent jab at Sony's recently-settled lawsuit that the company said was intended to protect PS3 from software piracy.

The lawsuit comes in the wake of millions of PlayStation Networks users' details being compromised after an illegal intrusion into the network. McPhadden Samac Tuovi LLP said 1 million Canadian user accounts were compromised.

At a press conference last week, Sony explained that stopping the PSN system had taken "more time than expected", but assured consumers that the service will be resumed within the month.
